Hi, yesterday the water in the bathroom sink was running and suddenly made a noise (like air maybe) and then the water pressure dropped to just a trickle. There are 2 sinks in the bathroom and the other one is fine as are all the other faucets in the house. I would appreciate any help, ideas, or advice on what to do. Thank you

The first thing I would do is remove the screen/aerator from the faucet and check for dirt - that is its job. If clogged, clean and reinstall. If that is not the problem, go further south and check your shut off valve - it may be clogged. It has to be one or the other since its neighbor sink is running fine. It should be an easy fix. Also, if you have a flex supply line, make sure it did not kink up for some reason.
